SUNRPC: Improve observability in svc_tcp_accept()
The -ENOMEM arm could fire repeatedly if the system runs low on
memory, so remove it.
Don't bother to trace -EAGAIN error events, since those fire after
a listener is created (with no work done) and once again after an
accept has been handled successfully (again, with no work done).
